JUST PICKED UP MY NEW 01 125 EXC
HAD A TAIL LIGHT INSTALLED TO MAKE IT
STREET LEGAL
WHEN I WENT OUT RIDING TJE FIRST NIGHT
I NOTICED THAT AS SOON AS I TOUCH THE REAR BRAKE TO TURN ON BRAKE LIGHT MY FRONT HEADLIGHT ALMOST GOES OUT EVEN AT FULL RPM
MY DEALER SAID THIS IS NORMAL AND NOTHING CAN BE DONE ABOUT IT
NONE OF MY OTHER BIKES EVER DID THIS AND THEY ALL HAD BRAKE LIGHTS INSTALLED FOR ENDURO RACING AND STREET LEGAL EVEN MY 1980 YZ250

With no battery, I agree with your dealer. I had a street legal '99 380exc, with no battery, and it would do the same thing.

The draw of your bulbs and filiments exceeds the output of your stator, plain and simple. Look in your manual for the output. Your rear bulb is probably pulling 25 watts when the brake is on, plus the headlight is either 35 or 55 watts.

If you have a 55 in the headlight then replace it with a 35. This should help. You may have to go to a bike shop to get the bulb as most autoparts stores carry 55 watt H4s.

One last possibility is you have a short in the brake light wiring you did and are bleeding off your power to some sink. Re-check your work if you find the manual says the stator has sufficient wattage to drive your total bulb load.
